Dura Ace Di2 ST-R9150 STI
The mechanical Di2 ST-R9150 Dual Control levers feature a refined hood shape with svelte shared ergonomics for more rider control in race conditions, regardless of braking choice. The ergonomically-enhanced Di2 shift levers produce a more defined shift click for a more intuitive feel and quicker shifting operation and expanded E-Tube customization allows every switch the option to independently turn on or off multi-shift. Thanks to the customizable function the levers fit any riding style and the carbon composite plastic hood material drops the weight of the whole construction.
